String
Theory: An Introduction to the Bosonic String by Joseph Gerard
Polchinski
This
is the most recent advanced text covering string theory as we currently
understand it. Since the classic and seminal Green, Schwarz and Witten
work featured below was last revised in 1988, major revolutions have occurred
in the understanding of string physics and mathematics. This first volume
covers basics string quantization, conformal field theory, the Polyakov
path integral, scattering amplitudes and T-duality. Prerequisites are
quantum field theory and general relativity.

String Theory: Superstring Theory and Beyond by Joseph Gerard Polchinski
This
second book of Polchinski's set covers supersymmetry and quantization
of the superstring and heterotic string, D-branes, strong coupling, compactification
and M-theory. Prerequisites are quantum field theory, general relativity
and the first book.

Superstring
Theory: Introduction by Micheal
B. Green, John H. Schwarz, Edward Witten Superstring
Theory is a two-volume set providing an mathematical intoduction
to beginning string theory. The first volume covers the basic bosonic
string, the basics of building a supersymmetric string theory, worldsheet
vs. spacetime supersymmetry, and tree amplitudes.

Superstring Theory: Loop Amplitudes Anomalies and Phenomenology by
by Micheal B. Green, John H. Schwarz, Edward Witten
The
second volume of the set Superstring Theory includes the basics of loop
amplitude calculations, the cancellation of quantum anomalies in particle
and string theory, and the compactification of extra spacetime dimensions.

Supersymmetric
Gauge Field Theory and String Theory (Graduate Student Series in Physics) by David Bailin, A. Love (Contributor)
An
introductory text for supersymmetry, supergravity, and supersymmetric
string theory, assuming prior knowledge of quantum field theory. Topics
include supersymmetry algebra and multiplets, Lagrangians for chiral superfields,
Lagrangians for vector superfields, pure supergravity, the bosonic string,
the heterotic string, direct construction of four-dimensional heterotic
string theories, and superstring interactions.

Superstrings: The First 15 Years of Superstring Theory by John H.
Schwarz, Editor
A
collection of early original papers in superstring theory, this volume
is instructive in both physics and in the history of physics. These are
the works that started superstring theory before it was a fully credible
enterprise as seen by the larger theoretical physics community. This is
an essential addition to the library of a string enthusiast.

Quantum
Field Theory of Point Particles and Strings by Brian Hatfield
A
lot of books on quantum field theory are filled with details that add
rigor for the expert at the expense of conciseness and clarity for the
student. This is a good book that gets to the point, suitable for someone
who wants to learn quantum field theory and the basics of string theory.
Even though the string section is not up to date with the latest developments,
the basics are well developed here, especially classical string theory,
a sadly neglected topic.

Supersymmetry and Supergravity (Princeton
Series in Physics) by Julius
Wess, Jonathan Bagger
This
widely acclaimed introduction to N = 1 supersymmetry and supergravity
is aimed at readers familiar with relativistic quantum field theory who
wish to learn about the supersymmetry algebra. In this new volume Supersymmetry
and Supergravity has been greatly expanded to include a detailed derivation
of the most general coupling of super- symmetric gauge theory to supergravity.
The final result is the starting point for phenomenological studies of
supersymmetric theories .

Introduction
to Supersymmetry by Peter Freund
A
brief introductory description of the new physical and mathematical ideas
involved in formulating supersymmetric theories. The basic ideas are worked
out in low space dimensionalities and techniques where the formulae do
not obscure the concepts.
